IMPROVEMENT IN CYLINDERS FOR CARDlNG-MAQHINES.

Specification forming part of Letters Patent No. 150,913, dated May 12, 1374; application filed February 2, 1874.

To all whom it may concern:

Be it known that I, FRANK TULLY, of Philadelphia, Pennsylvania, have invented an Iniprovement in Cardin g Engine Spindles, of which the following is a specification:

My invention relates to an improvement in the revolving and reciprocating spindles of the small card-rollers of carding-engines; and the object of my invention is to obviate the rapid deterioration of such spindles, an object which I attain by the combination of the flattened and hardened portion a of the spindle A, which projects from. the end of the card-roller M, with a hard steel bearing-disk, B, confined to the wheel D, as shown in the sectional view, Figure 1, of the accompanying drawing, or as illustrated in the modification, Fig. 4.

It may be stated in the outset that the ordinary spindles of small card-rollers are round, and have a feather or key adapted to a groove in the wheel, with which the spindle rotates, and in which it has to reciprocate. The rapid wearing away both of the portion of the spindle and the feather which pass through the wheel is a great source of annoyance and expense in mills in which carding-engines are used.

In order to obviate this difficulty, I make the spindle A at and near its outer end a flat on its opposite sides, the width of this flat tened portion of the spindle, hovever, being equal to the diameter of its round portion. D is the usual cog-wheel, having a projecting huh, (I, on which is formed a journal, adapted to bearings on the frame of the carding-en gine. This bearing-disk B, above alluded to, as being confined between the end of the huh (I of the wheel, and a screw-cap, E, is made of hardened steel, and has a central oblong opening, 0, of a size and shape conforming exact1y-with that of the flattened portion of the spindle,

which should also be made of steel or be casehardened.

As the wheel D rotates, the disk, which is notched to receive the end of the screw 2', and is thus prevented from turning independently of the wheel, must carry the spindle round with the latter, so that although a part of the round portion of the spindle enters the wheel, the main frictional bearing to resist the strain must be the flat portion of the spindle, and as the latter is case-hardened, and is acted on by the steel disk only, there must be comparatively little wear either on the disk or spindle as the latter reeiprocates in the former.

It may be remarked too that the oil poured from time to time on the spindle where it enters the wheel, will find its way to the space h, where it is retained as a supply for lubricating the flattened portion of the spindle and the disk.

The spindles of some of the card-rollers of a carding-engine must revolve with and reciprocate in two wheels, D and D, as shown in Fig. 4. Wherever the two wheels are necessary, I prefer to recess the outer face of the smaller wheel D for the reception of the disk E, which may be secured by ordinary screws, as shown.

I claim as my invention The combination of the rotating and reciprocatin g card-roller spindle A, flattened at the end, as set forth, the wheel D, and detachable block B secured to the wheel, and having an opening for receiving the flat end of the spindle, all as specified.

In testimony whereofI have signed my name to this specification in the presence of two subscribin g witnesses.
